Review of optical devices and systems based on microfluidics

Microfluidics is the basis of micro total analysis system (μTAS) and the research spotlight in Micro-Electro-Mechanical Systems (MEMS) now. With the development of microfluidics and the cooperation with other technologies,many new areas,especially microfluidic optical devices,come into being. It is possible that the miniaturization,arraying,low-cost and precise control of the optical devices are realized by the cooperation between microfluidic technology and optical devices. Some typical optical devices and applications are presented,including variable-focusing microlens,display device,optical switch,tunable optical fiber and grating.
